Trezor Bridge® is the official communication software that connects your Trezor hardware wallet to your web browser or desktop application. It acts as a secure, lightweight link that allows your computer to recognize and interact with your Trezor device without compromising security or privacy. Whether you’re managing crypto through Trezor Suite, using DeFi platforms, or verifying transactions, Trezor Bridge ensures smooth, safe, and uninterrupted communication between your wallet and your browser.
Trezor Bridge is a small, open-source service developed by the Trezor team. It runs quietly on your computer and facilitates communication between your Trezor hardware wallet and supported browsers. Without it, your browser would not be able to send or receive commands to your device, which means you couldn’t perform essential actions such as sending crypto, confirming transactions, or updating firmware.
By installing Trezor Bridge, you enable your device to communicate safely with web interfaces, all while keeping your private keys locked inside your hardware wallet. The bridge ensures that all data transfers remain secure, encrypted, and localized to your own computer.
Without Trezor Bridge, most browsers would not recognize your Trezor wallet. Installing it ensures a reliable connection every time you plug in your device.
Trezor Bridge operates as a local communication hub. It establishes a secure channel between your browser and the USB-connected Trezor hardware wallet. Here’s a simplified view of how it functions:
This design ensures full isolation of private data and cryptographic operations within the hardware wallet, maintaining the zero-trust security model.

Trezor Bridge has been engineered with privacy and safety as its highest priorities. It never transmits or stores any user data online and functions entirely within your local system environment.
localhost (127.0.0.1) — your own computer.This transparency and local-only operation minimize the attack surface and ensure user sovereignty over digital assets.
Trezor Bridge serves as a vital utility in various crypto management scenarios, such as:
Ensure the Bridge is installed and running. On Windows, check system tray icons. On macOS/Linux, verify that trezord service is active.
Restart your browser, disconnect and reconnect your Trezor, or disable any VPN/firewall temporarily blocking local ports.
Add udev rules for Trezor devices as described in the official documentation. This step allows USB detection for non-root users.
When Trezor releases new Bridge versions, always uninstall old versions first, then reinstall from the official page to ensure compatibility and performance.
trezor.io).Following these guidelines ensures that your Trezor environment remains uncompromised and fully secure.
Before Bridge, browser extensions or WebUSB APIs were commonly used for wallet communication. However, these methods lacked stability and were prone to permission errors or security risks. Trezor Bridge improves upon these by:
Trezor Bridge is open-source software, licensed and maintained publicly on GitHub. This means developers, researchers, and users can verify its security, contribute to improvements, and confirm that it does exactly what it claims — no more, no less.
This level of transparency aligns with Trezor’s mission: empowering users to control their own keys and data with full visibility.
The Trezor development team continuously refines the Bridge to improve compatibility with evolving browser APIs and system updates. Upcoming versions aim to deliver:
These upgrades ensure that Trezor Bridge remains an essential and future-proof layer of crypto communication.
